Gorbsky 2, 1 stowers institute for medical research, kansas city, mo 64110. The division of a cell occurs once in mitosis but twice in meiosis. Unique to this updated volume are chapters on analyzing the spindle assembly checkpoint in human cell culture, an analysis of cin, a functional analysis of the tubulin code in mitosis, employing crisprcas9 genome engineering to dissect the molecular requirements for mitosis, applying the auxin. In mitosis, the cells nucleus divides once to give rise to 2 genetically identical diploid cells. Mitosis and meiosis, part a, volume 144, a new volume in the methods in cell biology series, continues the legacy of this premier serial with quality chapters authored by leaders in the field. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information. The cell cycle, mitosis and meiosis learning objective this learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the same genetic component as the parent cell. Along with cytokinesis the division of the rest of a cell, mitosis results in a. Meiosis is a specialised type of cell division, the principal function of which is to produce sporesgametes sperm and eggs in mammals that have the haploid number of chromosomes. Identify the phase of the cell cycle which is the longest. Dna molecules in extended, uncondensed form chromatin. Meiosis begins while at first glance meiosis may appear the same as mitosis, these processes result in the formation of very different cell types.
Mitosis and meiosis are nuclear division processes that occur during cell division. A single cell divides into two identical daughter cells. This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the same genetic component as the parent cell. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Meiosis and mitosis covers chapters on meiosis and mitosis. Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Mitosis involves the division of body cells, while meiosis involves the division of sex cells.
